简要总结
The purpose of this study is to evaluate the safety and tolerability of AGS67E in subjects with acute myeloid leukemia (AML) and determine a safe dose for future development. In addition, this study will assess the pharmacokinetics (PK), the immunogenicity, and the anti-leukemic activity of AGS67E.
详细描述
The study will sequentially evaluate AGS67E given as a 30 minute intravenous (IV) infusion in two different schedules: once every 3 weeks (Q3) and then once weekly for 3 weeks.
The dose escalation follows a 3 + 3 design.
The Data Review Team may expand any dose level or intermediate dose level that has been deemed safe and resulted in at least one subject with a Composite Complete Remission (CRc). An expansion cohort may enroll up to 15 subjects.
